Everbuild Everflex 125 One Hour Caulk 300ml

The Everbuild Everflex 125 One Hour Caulk is an elite architectural-grade acrylic sealant engineered to deliver superior mechanical reliability and rapid preparation for interior decorating. This specialized caulk addresses the critical need for a flexible, paintable filler that can keep pace with fast-moving professional renovation projects.

Constructed for maximum efficiency, the 125 One Hour Caulk utilizes an advanced fast-drying formula that allows tradespeople to fill gaps and cracks and begin painting in as little as sixty minutes. Its technical design prioritizes permanent flexibility, boasting a +/- 12.5% flexibility factor that ensures the filler remains intact during the natural expansion and contraction of building materials. This makes it an ideal solution for internal perimeter joints around wood or plaster where standard fillers might fail or crack over time.

Key Benefits:

Optimized Decorating Workflow: The one-hour overpaintable feature allows for same-day filling and painting, significantly reducing labor time.
Superior Joint Integrity: Permanently flexible properties prevent the sealant from becoming brittle, maintaining a clean seal through minor structural shifts.
Professional Finish: Dries to a smooth, non-slump consistency that requires no sanding, providing a perfect base for interior paints.
Versatile Material Adhesion: Bonds effectively to most common interior construction materials including wood, plaster, and masonry.

Application Instructions:

Ensure all surfaces are clean, dry, and free from dust, grease, or loose debris.
Cut the applicator nozzle at a 45-degree angle to the desired bead size.
Insert the cartridge into a professional caulking gun and apply the caulk steadily into the gap.
Smooth the surface using a damp cloth or joint finishing tool within 5–10 minutes.
Allow to dry for at least one hour before overpainting with water-based or solvent-based paints.

Pro Tips:

Deep Gaps: For very deep gaps, apply the caulk in layers or use a suitable backer rod to ensure optimal drying and flexibility.
Cleaning Residual Caulk: Clean up any excess wet caulk immediately with warm water; dried material must be removed mechanically.
Paint Compatibility: While paintable in one hour, thicker beads may require slightly longer in cold or damp conditions before final decoration.
